AI in everything is the problem
Current AI is just pattern recognition on steroids, there is still no real intelligence in any AI system. The single word tagging of pictures has been known to be suboptimal for a long time now and yet it is still done. If there was any of the I in AI then multiple word tags should not be an issue as it should be capable of recognition of multiple items in one picture.
Additionally, and I can't find the fine article that was in this exalted place, you can carry a tag around with you and be misidentified as the tag because the AI 'learns' the tag as well as the picture.
Certainly artificial, definitely not yet intelligent.
